My invention relates to an improvement in basin-wastes, the object being to providea device of that character by means of which the chain and stopper contrivances formerlyemployed are abolished and devices consisting in a system of levers anr'anged4 to operate thel stopper from beneath the basin are substituted therefor, said devices insuring perfect immunity from noxious sewer-gases, adapted to a wide arrangement of adjustment, as circumstances may necessitate, and combiningease of operation and durability in use with simplicity of construction, and hence cheapness of production. Y With these ends in view my invention consists in certain details of construction and combinations of parts, as will be hereinafter described, and pointed ont in the claims.

In the accompanying drawings, Figure 1 is a view, partly in section and partly in elevation, of a device constructed in accordance with my invention and applied to a stationary washbasin. Fig..2 is an end view of the horizontal arm in which the lever is fulcrumed, and Fig. 3 is a detail view of the cap tling over the free end of said arm.

A represents a wash basin or bowl, mounted in a wash-stand, B, and provided at its lower central portion with a collar, O, having an exteriorly screw-threaded shank, D,`a slightlybeveled valve-seat, E, and a nut, F, which latter is designed to be screwed on the shank D after it has been inserted in the bowl, to impinge against the lower face, G, thereof, and

hold the collar O tightly therein, and prevent the escape of water around its edge, instead of through the outlet or valve-seat E.

H is a valve,- having a sufficiently tapering outer edge, A', to t within the valve-seat E, and is provided with a stem, I, having strainers J cast integral therewith or attached thereto. The extreme lower end of the valvestem is screw-threaded, to make connection with a lever, K, which communicates the motion of the operatiugrod L to the valve H, as hereinafter described. 4

M is an arml cast integral with or attached to the pipe N, the upperand lower ends of which are respectively secured to the lower end of the shank D of thecollar O and the waste-pipe O. The arm- M, which opens into pipe N, hasa slight downward inclination, to prevent the accumulation therein of any water or any foreign substance which would interfere with the free operation of the lever K, which is fulcrumed between the outer end of Vthe arm and a cap, P, fitting thereover. The outer end of the arm M is countersunk at Q to receive the forward portion of a ball, R, located on the lever K, and which isV retained in the countersink by an axially-perforated cap, l?,1 interiorly adapted to iit over the outer portion of the said ball. The arm M and the cap P are respectively screw-threaded on their inner and outer faces, whereby the cap is adapted to be screwed over the end of the arm,as before described, and the friction between the countersink Q, the interior walls of cap P, and the ball R may be varied as may be found necessary by the manipulation of the ball.

The forward end of lever K is connected, as will be hereinafter described, with the stem I of the valve H. The rear end thereof ,is`r connected to the rod O', and is fulcrumed between these two points byaball-and-socket-joint connection formed by the combination with the inner end of the arm M, the cap P, and the ball R.

Two lugs, T, formed just within the countersink Q, together form an elongated aperture adapted to receive a lug or shoulder, U, having vertical sides and located on thelever. The effect of this construction is to modify the motion usually attributed to the ball-and-'socket IOO ing its outer end vertically perforated and internally screw-threaded at X, to admit thelower and screw-threaded end of the valve-stem I of the valve H. This connection between the lever K and the valve-stem I, I esteem of great importance, as I am enabled to unscrew the valve stem and withdraw the valve to be cleaned, and to relieve the strainers ot' any substances which they may have collected. At the same time the valve-stem is so secured to the lever that any sudden impulse given to it will not displace the valve.

The rod L, by means of which the valve is primarily operated, is situated at any convenient point on the top of the stand B,and is operated through a collar, Y, having a screwshank, Z, cast integral therewith, and clamped to the stand-top by a nut, B', screwed on the shank Z. The ripper end of the said operatingrod L is provided with an ornamental knob, C2, which, in the normal and closed position of the Valve, is raised a slight distance above the collar Y.

Connection is made between the lower end of the operating-rod L and the lever K by the adjustable arm C', one end of which is counterbored at D' to receive a thumb screw, E', which may be manipulated to enter and engage with the lower end of the operating-rod, which is received within a vertical perforation, F', in the arm C', and at right angles to the counterbore D'. The end ot' lever K is received in a perforation, G', which has such location in the arm that when the rod L and lever K are connected in the arm C they are at right angles to each other.

It will be also observed that the rod and lever can be accommodated to basins of different sizes and at different positions on the washstand, as may be necessary or convenient, by changing their adjustment in the connectingarm C'.

In the foregoin g description I have described in detail each of the levers and their respective adjustments and connections, which together constitute my invention and from the foregoing it will be apparent that a downward pressure on theknob G2( which, as before stated, is raised a slight distance above the collar Y) will depress the inner and raise the outer end of lever K, and raise the valve H and allow the water in the bowl to escape. The weight of these portions of the device, located respectivel y to the right and left of the fulcrum, is nearly equal, that end of the lever to which the valve is attached being enough heavier to maintain the valve closed as its normal position,while the power required to overcome the eXtra weightis very slight, and the friction of the ball R in its socket will hold the valve open after it has once been raised through the knob C2. rlhe levers being connected, the movement submitted through them is apositive one; and inasmuch as the force of Agravi ty depen ded on in some devices of this character is a secobtain a certainty of action and a surety of the performance ascribed heretofore unknown to devices of equally simple construction.

I would have it understood that I do not limit myself to the particular form of construction shown and described, brit hold myself at liberty to make such changes and alterations as fairly fall within and do not transcend the spirit of my invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In abasin-waste, the combination, with a lever having a ball attached thereto, of a hollow arm in which the forward end of the lever plays and which has its free end socketed, and an axially-perforated cap adapted to tit over the end of the said hollow arm and hold the ball in the socket thereof, substantially as set forth.

2. In a basinwaste, the combination, with a hollow arm in open communication with the waste-pipe and having vertical lugs located within its outer end, of a lever-arm having a squared block secured thereto, or made integral therewith, said block being adapted to be received within the lugs aforesaid and to limit the lever to a vertical movement, substantially as set forth.

3. In a basin-waste, the combination, with a hollow arm in open communication with the waste-pipe and having vertical lugs cast within its outer end, which is soeketed, of a leverarm provided with a squared block and a ball adapted to be received, respectively,within the socket and lugs of the hollow arm, and a device to retain the said ball within the socket of the arm, as aforesaid, substantially as set forth.

4. In a basin-waste, the combination, with a lever adapted to be actuated in vertical reciprocatin g movement and provided with a screwthreaded perforation at its forward end, of a valve the stem of which is adapted to be received within the lever-perforation, substantially as set forth.

5. In a basin-waste, the combination, with a hollow arm communicating with the wastepipe, and a lever having its fulcrum in the outer end of said hollow arm, of a valve-stem screw-threaded at its lower end, and a block or connecting device provided with screwthreaded openings for the valve-stein and the lever, substantially as set forth.
